Abstract
Provided are polyaramid polymers and films made from the polymers, comprising repeat units of the condensation product of a fluorovinylether functionalized aromatic diacid chloride and an aromatic diamine, and methods to make the films.
Claims17
A film comprising a polymer comprising a fluorovinyl ether functionalized aromatic repeat unit represented by the structure (I)
- wherein,
- Ar represents a benzene or naphthalene radical;
- each R is independently H, C1-C10 alkyl, C5-C15 aryl, C6-C20 arylalkyl;
- OH, or a radical represented by the structure (II)
- with the proviso that only one R can be OH or the radical represented by the structure (II);
- each R1 is independently H, C1-C10 alkyl, C5-C15 aryl, C6-C20 arylalkyl;
- X is O or CF2;
- Z is H, Cl, or Br;
- a=0 or 1;
- and,
- Q is represented by the structure (Ia)
- wherein q=0-10;
- Y is O or CF2;
- Rf1 is (CF2)n, wherein n is 0-10;
- and,
- Rf2 is (CF2)p, wherein p is 0-10, with the proviso that when p is 0, Y is CF2.
